Frequently Asked Questions

cjru.ca is not currently classified as a disposable email domain in our database. The trust signals on this page show what we did find — a domain can still be low-trust without being a known throwaway service.
It is a 0–100 summary of everything we know about the domain: whether it runs a real website, how old it is, who registered it, which mail servers it uses, whether it sits on infrastructure shared with known throwaway services, and how its domain ending scores for abuse. Every signal that moved the number is listed on this page.
cjru.ca was first registered on 6 January 2015, which makes it 11y 7m old, older than 77% of the domains in our catalogue. Registration dates come from the domain's WHOIS/RDAP record.
Age is a cost signal. Setting up throwaway infrastructure is cheap, but waiting years is not, so domains registered in the last few weeks are heavily over-represented in disposable signups, phishing and short-lived spam runs. It works in one direction only: a new domain is a reason to look closer, while an old domain is a weak positive rather than a guarantee — expired domains get bought and repurposed precisely because their age looks reassuring.
Call the MailRook API from your signup form and check the address before you create the account. You get the same classification and trust score you see on this page, in a single request, and you can decide whether to allow, challenge or block.
